Inasmuch as you, like me, may have missed xslide’s “Template” menu when editing XSLT using Emacs’ nXML-mode, I’ve made available my “xslide2” XSLT mode for Emacs that I’ve been using for a while. This new xslide is a derived mode that uses nXML-mode for nearly everything and adds back some of the XSLT-specific parts of xslide.
